Transformations and Congruence · Geometry & Measurement

Rigid Motions in the Plane

Defining congruence through the lenses of translations, reflections, and rotations.

Key Questions

  1. 1Which properties of a figure remain invariant under a reflection versus a translation?
  2. 2How can any congruence be described as a sequence of rigid motions?
  3. 3Why do we define congruence through motion rather than just measurement?
